improved stop motion operating in conjunction with the loom harness to be set in operation upon breaking of a harness strap.

In the accompanying drawings:

Figure 1 is a diagrammatic view illustrating my invention in association with a loom harness and the usual drop wires.

Figure 2 is a sectional detail view of a harness actuated plunger means.

Figure 3 is an elevational view of the structure of Figure 2, but illustrating the broken harness engaged therewith.

Figure 4 is a top view of a harness engaging bar.

projection. The tension of the spring 44 issuch as to normally hold the bar lever l8 in the position of Figure 2; but ,the spring yields when the harness I2 drops upon the bar, as in Figure 3, to

, its attached wire 36.

Figure 6 is a top view of the lever structure of Figure 5, and

The usual drop wires are indicated at [4 in association with an oscillating stop motion bar [6.

Underneath the harness I0 is mounted. a bar lever l8 of U-shaped contour and having its ends pivotally connected at with a head 22 fixed to a bar or post 24 which may ibe attached to the loom frame structure (not shown).

In Figures 2 and 3 a plunger 26 is located underneath the 'bar lever l8 to be thrust downwardly when the harness drops onto the bar lever. This :bar lever is provided with a flange 28 .arranged to constitute a pusher element for the plunger 26. The plunger is slida'bly guided in a tubular housing 30 adjustably mounted in an opening 32 in a projection 34 on the post 24. A flexible wire 36 is attached to the head 38 on the plunger 26, Which wire is slidably guided in a coiled wire tube 40, such as a Bowden wire.

The other end of the wire 36 is inserted in an axial bore in one end of a link 48 slidably guided by a tubular housing '50. This housing-is ad- 'justably connected. with a bracket 52, which bracket is attached to a support 54, which may comprise the stop motion stand of the loom. A

set screw 56 is threaded into the bracket 52 for engagement with the housing 50 to fixedly relate the latter to the bracket. 7

A flange 58 is threaded on the link 48 and serves as a support for one end of a compression spring '60 having its other end abutting the top end of the housing 50 to normally hold the link 48 in the position shown. The tube is secured in a plug 62 threaded into the lower end of the housing 50. A set screw 64 is threaded into the plu 62 'for engagement with the tube 40.

To the upper end of the link 48 is pivotally connected one end of a lever 66 pivotally connected intermediateits ends, as at 68, with an upstanding arm 10 on the bracket 52. To the other end of the lever 68 is attached a blade 12 in the nature of a drop wire. This blade extends downwardly betweencertain of the drop wires 14 arranged to fall into the path of the stop motion bar l6. Normally the blade 12 is spaced upwardly from the vention operates to stop theloom upon breaking A plug 42 is threaded into the lower end of the housing 30 and constitutes an abutment for one end of a compression spring 44 engaging the head 38, in addition to serving as a support for of a harness strap. The device is easily attached to the loom and operates sufiiciently as an adjunct to the usual drop wire stop motion.

Withoutfurther elaboration, the foregoing will 1. A stop motion device for use with a loom having a harness, and a stop motion member, comprising a first pivoted lever mounted beneath the harness to be engaged and pivoted'thereby when the harness breaks, a spring pressed plunger slidably mounted beneath and engagingv the first lever and adapted to normally hold the same in an inoperative position, a blade movable to a posithe loom, a second pivoted lever carrying the blade, 2, spring pressed link connected with the second lever to normally hold the lever and blade in inoperative position with respect to the stop motion member, and a flexible wire connection between the plunger and the link to actuate the link, the second lever and the blade to move the blade into the pathvof the stop motion member when the first membered lever is engaged and moved by a broken harness to actuate the plunger and flexible wire.

2. A stop motion device for use with a loom having a harness, and a stop motion member, comprising a, flanged bar lever pivoted beneath the harness to be engaged thereby when the harness breaks, a spring pressed adjustable plunger slidably mounted beneath and engaging the flange of the bar lever to normally hold the same in an inoperative position, a blade movable to a position in the path of the stop motion member of the loom, a pivoted lever carrying the blade, a spring pressed link connected with the pivoted lever to normally hold the lever and blade in inoperative position with respect to the stop motion member, a flexible wire connection between the plunger and the link to actuate the lever, the Divoted lever, and the blade to move the blade into the path of the stop motion member when the bar lever is engaged and moved by a broken harness to actuate the plunger and flexible wire, and means for adjusting the action of said link.
